Info: 60 Vegetarian Capsules

Py-Plex is temporarily unavailable from the manufacturer, possibly until late 2024. Please see AOR Gastro Relief or Protocol Ulcetrol.

Traditionally used as gastro-protective herbs, licorice, marshmallow root, and slippery elm aid to soothe, coat, and protect the gastrointestinal system. In addition, mastic gum (a resin of the Pistacia lentiscus tree) has been shown to kill the H. Pylori bacteria and protect against the formation of gastric and duodenal ulcers. It also has anti-inflammatory and antioxidant properties which may help with inflammatory bowel disease (IBD).

Product Notes:

Plagued by H. pylori bacteria or peptic ulcers? Py-Plex by Douglas Laboratories targets the Helicobacter pylori bacteria, which unlike most bacteria, can survive in the acidic environment of the stomach and can lead to painful inflammation and erosion of the stomach lining.

Naming Note: This Douglas Laboratories formulation was previously marketed as 'Pylori-Plex'.

500 mg Mastic Gum (Pistacia lentiscus)
